In response to a recent report by the Pentagon that a ground invasion would be the only way to eliminate North Korea’s nuclear capabilities, 15 Democratic members of Congress have spoken out against the idea of a military conflict — but one top Democrat says it could be a possibility.

When asked about her support for a ground invasion on CNN’s State of the Union Sunday, House Minority Leader Nancy Pelosi said she would be open to it as a last resort.

“Well, I think we have to exhaust every other remedy,” Pelosi said. “North Korea’s behavior has to be stopped, reversed — they cannot have a nuclear weapon.”

Pelosi went on to say her concerns about North Korea extend to how the country sells its nuclear weapons, in addition to developing them for its own use.
